Refactor archival strategies in FILE_ARCHIVER package

Browse Source 
- Removed CURRENT_MONTH_ONLY strategy, replacing it with MINIMUM_AGE_MONTHS = 0 for current month retention.
- Updated validation logic to allow MINIMUM_AGE_MONTHS to be non-negative.
- Consolidated documentation to reflect changes in archival strategies.
- Adjusted rollback script to reset all archival parameters to NULL for 25 Release 01 tables.
- Enhanced README and installation scripts to clarify new configuration requirements and usage examples.
- Updated version history to indicate breaking changes and migration steps for existing configurations.
